Hi,

As stated in the datasheet, the analog input range for LT2209 is typically 1.5 or 2.25 Vp-p. Can you try increasing your input if it shows an improvement?

Additionally, you can also refer to the user guide DC1281A-LTC2209 Evaluation Kit Quick Start Guide (analog.com). The 1281A demo board has several versions, kindly check if you are using the correct one that match your sampling rate and input frequency.

Hope this helps.

Regards,

Meriam
